The following names were used for tropical storms that formed in the North Pacific Ocean east of 140°W during 1960. The names came from a series of four rotating lists. Names were used one after the other without regard to year, and when the bottom of one list was reached, the next named storm received the name at the top of the next list. This was the first season in which tropical storms in the basin were officially given names.No tropical storms formed in the North Pacific between 140°W and the International Date Line in 1960. Had there been, their names would have been drawn from the Western Pacific typhoon naming list.
